The microtiter plate provided in this kit has been pre-coated with F-TESTO. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to F-TESTO. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of F-TESTO in the samples is then determined by comparing the OD of the samples to the standard curve.\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"ELK Bio","offers":[{"title":"48T","offer_id":45200827809971,"sku":"ELK9584-48","price":448.0,"currency_code":"CAD","in_stock":true},{"title":"96T","offer_id":45200827842739,"sku":"ELK9584-96","price":641.2,"currency_code":"CAD","in_stock":true},{"title":"96T*5","offer_id":45200827875507,"sku":"ELK9584-5x96","price":2725.8,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_360x_e7ca7441-b32b-4471-a93a-584256f3b8b2.png?v=1767065035","url":"https:\/\/afsbio.com\/products\/f-testo-free-testosterone-elisa-kit-elk9584","provider":"AFSBio Inc.","version":"1.0","type":"link"}
